GAS BURNER non; masseuse;

Application filed April 11,

This invention relates broadly to gas burners, and has more particular reference to a gas burner for incubators.

burner capable of using either artificial or natural gas, which will consume but little gas, will maintain a steady heat, will be safe, clean, odorless and otherwise conducive to better hatching.

Other objects and advantages of the invention will becomeapparent during a study of the following description takes in connection with the accompanying drawings;

V Figure 1 is a side elevational View of our improved burner, v

Figure 2 is a fragmentary elevational View for more clearly illustrating the chimney,

Figure 8 is a transverse vertical sectional View taken through the burner, I

Figure 4 is a detail sectional view taken substantially on the line t-4:of Figure 1,'

Figure 5 is a similar view taken substantially on the line 5-5 of Figure 3,

Figure 6 is a detail sectional view taken on the line 6-6 of Figure 3. i V

Figure 7 is a detail sectional view taken substantially on the line 77 of Figure 3.

With reference more in detail to the draw ings, it will be seen that our improved burner comprises a substantially L-shaped tubular member 5 including the horizontal arm 6 and the vertical arm 7. A supporting plate 8 is provided with an openingin the center thereof for receiving the upper end of the arm 7 and the plate adjacent the opening is provided with a plurality of circumferentially spaced angular lugs or brackets 9 adapted for disposition about the arm 7 and retained in clamped engagement with the arm 7 for retaining theplate 8 in an adjusted positionon said arm through the medium of a split clamping ring 10 of conventional structure.

The plate is providedwith an annular up- 939'; Serial m; 443,486i

It Will be also apparent that the chimney is adjustable on the arm 7 further enhancing a burner of this character.

It is thought that from the foregoing description, taken in connection with the accompanying drawings a clear understanding of the operation, construction, utility and advantages of a burner of this character will be had by those skilled in the art Without a more detailed description.

Even though We have herein shown and described the preferred embodiment of our invention, it is to be understood that the same is susceptible to changes fully comprehended by the s irit of the inventionand as herein describe and the scope of the appended claims.

Having thus described our invention, what we claim as new-is:

1. In a gas burner of the class-described a substantially 'L-sh'aped tubular conduit opened at its upper end, aburner head on one end of said conduit, a chimney, means for adjustably mounting said chimney on said conduit at said one end, said conduit being internally threaded at its opposite end, a partition in said conduit inwardly from said threaded end,-said partition having a conical recess therein merging at its apex into an opening extending through said partition, a jet including ahead receivable in said recess, said hcadbeing perforatedwhereby gas from a suitable supply maybe forced -through said head into saidopening for passage through the conduit to said burner head.

2. In a gas burner of the class described a substantially L-shaped tubular conduit opened at its upper end, a burnerhead on one end of said conduit,a chimney, means for adjust-ably mounting said chimneyon said con- 'duit at said'one end, said conduit being interternally threaded at its opposite end, a par tition in said conduit inwardly from said threaded end, said partition having a conical recess therein merging at its apex into an opening extending through saidpartition, a jet including a perforated head receivable in said recess, said conduit inwardly from said partition provided with an air intake port, and a sleeve slid'ableon said conduit for controlling said port. s i

3. A gas burner comprising a conduit, a burner head on one end ofsaid conduit, a chimney,means for adj ustably mounting said chimney on said conduit at said one end, an apertured partition arranged in said conduit, intermediate the ends of the conduit, said partition provided with a recess,a jet extending into the conduit and including a tures.
